2,706,301 BRUSHING, CLEANING, AND SCRAPING MACHINES Philip A. Gango,Farmington, W. Va. Application October 24, 1949, Serial No. 123,119 3Claims. (Cl. 15-23) This invention relates to improvements in cleaning,abrading and/or scraping machines, particularly well adapted forcleaning butcher blocks, etc.

The primary object of this invention is the provision of a very compact,durable and efficient cleaning and scraping machine having an improvedbrush head mounting means.

A further object of this invention is the provision of improved meansfor maintaining scraper or brush blades in detachable relation within abrush head.

Other objects and advantages of the invention will appear in thefollowing detailed description.

In the accompanying drawings, forming a part of this specification andwherein similar reference characters designate corresponding partsthruout the several views-- Figure 1 is a side elevation of the improvedcleaning machine.

Figure 2 is an end elevation of the improved cleaning machine.

Figure 3 is a bottom plan view of the improved brush head mountingstructure.

Figure 4 is a cross sectional view taken substantially on the line 44 ofFigure 3, showing the brush or cleaning head details and drive gearingconnected to the same.

Figures 5 and 6 are cross sectional views taken substantially on therespective lines 5-5 and 6-6 shown in Figure 4 of the drawings.

In the drawings, wherein for the purpose of illustration are shownpreferred and modified forms of the invention, the letter A maygenerally designate the im- It includes a casing structure B; motor Cassociated therewith, and a rotary cleaning or brush head E which may beused selectively therewith", said brush head being driven by means Fconnected to the motor C.

The casing structure B is preferably of cast aluminum or other suitablematerial, including a top wall 10, end walls 11 and 12, and side walls13 and 14. These walls may be cast integral and the compartment 15formed thereby is open at the bottom of the casing.

The motor C may be of any approved type, and in this connection it willbe noted that its mounting is on the top wall 10, as shown in myassigned U. S. Patent 1,702,007. The motor may be mounted upon aninsulating pad on top of the wall 10, by any suitable means (not shown).The motor C includes a shaft 21 extending into a gear box 22 housing themeans F.

The brush head E is mounted upon a horizontal axis within thecompartment 15, with bearings upon the end walls so that the brushes orscraper elements thereof project slightly below the compartment. Thedepth of brushing or scraping is regulated by depth regulating members25 and 26, best shown, as to structure and mounting, in Figures 1 and 2,for vertical adjustment upon the side walls 13 and 14.

The depth regulating members 25 and 26 are preferably of the samematerial as the casing structure. I prefer aluminum and each includes abody portion 27 overlying the outer surface of the side wall and at thebottom thereof it is flanged inwardly at 28 to define a groove whichreceives the lower marginal portions of the side walls and presentsdownwardly facing convex surface 29 which at times may engage thebutcher block or the surfaces to be scraped or cleaned; the convexsurfacing preventing injury thereto. The body portion 27 of each guidemember is provided at its ends with upstanding attaching portions 31slotted at 32 to receive clamping screws 33 attached to the side walls,as shown. The slots 32 are vertical and enable the members 25 and 26 tobe vertically regulated upon the side walls of the casing structure forthe purpose of limiting the cleaning depth of the brush head.

Referring to the means F for driving the brush head, the same includes apinion 40 keyed upon the shaft 21 of the motor C and meshing with anidler gear 41 mounted upon a shaft 42 which in turn is secured upon themounting wall 43. The gear 41 meshes with another gear 45 keyed upon ashaft 46 which bears within a bushing 47 mounted upon the end wall 12 ofthe casing B.

The gearing is enclosed in gear box 22 which includes the mounting wall43 and a cover 50, both of which are bolted as at 51 to the end wall 12.Bushing 47 in which the shaft 46 bears is mounted not only upon the endwall 12 but also upon the gear box wall 43, as shown in Figure 4. Theshaft 46 extends into the compartment 15 of the casing structure whereit is intended to be secured to the brush head.

The wall 11 of the casing is provided with a bushing 70 apertured at 71to receive a detachable endwise removable shaft 105. At its opposite endthe shaft has a bearing extension received in the opening of adiscshaped member 78. The disc 78 receives the end of the gear shaft 46therein and is keyed thereto by a bolt or set screw 80.

The brush E furthermore includes a tubular frame or body portion whichreceives the shaft 105 therethru. The tubular body 110 at the endsthereof has annular flanges 111 and 112. The tubular body 110 betweenthe flanges 111 and 112 may be provided with other blades or brushstabilizing flanges 114 and 115. These flanges are all radially slottedto receive the blades 116 and 117. The blade 116 differs only from theblade 117 in that the latter is provided with a straight scraping edgeand the edge of the blade 116 may be saw toothed, or brush tufts 101substituted, as shown in Figure 2. The blades 116 and 117 at the endsthereof are reduced for fitting in the radial slots of the flanges 111and 112 wherein they are secured by detachable rings 120 and 121. Theformer is secured at 122 against accidental detachment and the latter at123, both by means of bolt structures.

The brush head E may be keyed to the disc 78 by means of an L-shapedportion extending from and rigid with the ring 121, shown in Figure 3,an extension portion of which fits within a suitable slot 131 disposedacross the outer periphery of the disc 78 as shown in Figure 12, and aright angled portion which engages the outer side of the disc 78*.

The machine is provided with U-shaped handle structures and 141detachably mounted at 142 upon the side walls and extending beyond theend walls for hand engagement; the extreme ends thereof being providedwith curled hand engaging portions 143.

It is believed the operation of the brush will be apparent from theforegoing. The vertically adjustable side wall members 25 and 26regulate the scraping and brushing depth, as is apparent, and the brushheads, as well as the individual blade members or brush members thereof,may be readily detached. All of the parts may be disassembled for readycleaning, as will be quite apparent from the foregoing.

Various changes in the shape, size and arrangement of parts may be madeto the form of the invention herein shown and described withoutdeparting from the spirit of the invention or the scope of the followingclaims.
